-
Secure cloud sandboxes where AI agents run code, use a filesystem and terminal, and browse, isolated from your own machines.
- More widely used (Gid Score 60 vs 24)
-
Connects AI agents to 1,000+ apps and APIs with managed authentication, tool search and a sandboxed workbench, so agents can take actions in tools like GitHub, Slack and Gmail.
